How can i make a sort of cloth/leather object?
Example with Cloth Simulation ...


add Cylinder, add horizontal Loop Cuts Ctrl+R 10, to get square net
Invert Selection I
Assign these top/bottom loops (vertices) to a Vertex Group under Properties Editor &gt; Dara &gt; Vertex Group
Add Cloth Simulation and under Cloth Sim Properties &gt; Shape &gt; Pin &gt; choose vertex group
I animated top part with a Hook modifier assigned to Empty, but you can parent Cylinder's top (or bottom) vertices to any specific part of your character
For a final touch I added Subdivision Surface modifier
